OILING DEVICE FOR' GASOLENE-ENGINES;

Specification of Letters Patent- Patented an. 23,1912- Applieationfiled October 11, 1907. Serial No. 896,873. i v

In the preferred form of the invention the oiling device is extremely simple in construction and comprises an oil receptacle located beneath the open end of and means operating intermittently in timed To all whom it may concern:

e it known that we, WILLIAM E. An Ms and WILLIAM J. MURRAY, citizens of the United States, residing at Salem and Beverly, respectively, in the county of Essex and State of Massachusetts, have inventedi' certain new and useful llnprovements in Oiling Devices for Gasolene-Engines; and We do hereby declare the following to be a full, clear, and exact description of the in vention, such as will enable others skilled in the artto which itappertains to make and a use the same.

he present invention relates to an improved oiling apparatus, and is' de'signed primarily for use in connection with hydrocarbon motors, although in its broader as pectsit is also capable of use with other .forms of apparatus.

The object of the present invention is to provide an oiling. apparatus by which a definite amount of oil can be supplied at regular intervals and in a certain and reia le manner to parts of machinery which means being provided for rotating the shaft in timed relation to the movements of the crank shaft and pistons, and suitably located openings being provided in the shaft and ushings which during the revolution of the sha t come into reglster and thereby allow jets of oil to escape from the hollow shaft upwardly into the open ends of the cyliners. I

The present invention will he clearly understood'from an inspection of the accompanying drawings in whichigure 1 is a view in side elevation partly piston of hydro-carbon motors or similarly constructed-apparat-us can be supplied with oil in a satisfactory manner.

With the above object in View the present invention broadly considered contemplates the provision of an oiling de'vicejso located with relation to the part to be oiled as to be separated therefrom by an intervening space and means .whereby the oi-ing device is caused to operate in timed relation-to the moving parts which, are to he oiled, to intermittently throw a jet of oil upon said parts.

he motor illustrated in the drawings is of Well-known construction and need not be specifically described, 1 indicating the cylinders, 2 t0 the pistons working therein, 3 the crank shaft connected by the piston rods ended cylinder and a piston working therein, the invention contemplates the provision of an oiling device located at a suitable distance from the cylinder, and means for o erating the oiling device in timed relation to the movements of the piston to intermittently throw a jet of oil into the open end pletely incloses the crank shaft.

of the cylinder. he improved oiling apparatus illustrated in the drawingscompriscs an oil receptacle in the form of a.ho'llow shaft 6,'"which is located in the lower. part of the crank casing directly beneath the crank shaft, and is shaft revolves, register successively with the holes 10, ll and 12. One of these holes is indicated at 1,3. ,The'holeslO, 11 and 12 are so arranged that during the rotation of the shaft GIthr'ee jets of oil are allowed to escape successively from the shaft; one jet being thrown directly upwardlagainst the end of the pistonrod ,when it is in its lowest position, and (the otherjets. being 'thrown obliquely upward against-opposite sides of the cylinder walls. vThe holes 13 in the shaft 6 are so arranged, and the, shaft is rotated in such timed relation with the crankshaft that a jet of oil is thrown upwardly into the open endof a cylinder at tir'nes when'the crank pin is out of the path of the jet, one jet, for instance, being thrown upwardly into'the op'en end of the cylinder when a crank pin isinthe 'positionillustrated in Fig. 2-, and the'otherjet being thrown upwardly into the open, end of the cylinder when the crank pin is 'in a diametrically opposite position," v,

' The requisite amount of foil is supplied to the shaft 6 under pressure bymeans of a suitable pump indicatedat 14, which is actuated frtiiii t'he c'rank shaft by means of a belt 15 passing over pulleys secured to the crank shaft and tothe shaft of the piunp. The pump takes its oil from a reservoir 16"through a pipe 17, and delivers the oil to the shaft 6 through a'pipe 19 and stufiing box 19 at one end of the shaft thepipe 18 being so'connected to the shaft 6, as to permit the rotation of the latter; To maintain the oil .in the shaft 6 at a constant pressure a by-pass is provided [by means of a pipe 20 leading from the pipe 1S'to a returnpipe 21, and-thisby-paem is provided with a pressure regulating valve indicated at 22. The surplus oil; which, collects in the lower portion of the crank cas ng is returned to the reservoirflfi by'means of return pipes 21. and the reservoir is provided with a suitable strainer Q J-for the returned .By means of the apparatus above described, a definite, predetermined amount of oil is supplied with certainty and at the desired times to the walls of the cylinders, and,the cylinders and pistons are lubricated in a satisfactory manner without any liability of either too little 'or too much oil being supplied theneto.

The nature and scope of the present invention having been indicated, and the preferred form of the invention having been described, what is claimed is I 1. The combination with an open-ended cylinder and a piston working therein, of an oilreceptacle provided with an oil discharge orifioe, said orifice being located at all times withoutthe cylinder, nieans'for supplying oil to said receptacle under pressure and means operating in timed relation to the movement of the piston to permit a jet of oil-to escape intermittently from said vorifice into, the open end of the cylinder,

substantially as described. a

.2. The combination with an open ended cylinder and a piston working therein, of a hollow shaft located beyond the open end of the cylinder, a sleeve through which the shaft passes, means for rotating the shaft in timed relation to the movement of the piston, and means for supplying oil to the shaft under pressure, said sleeve and shaft being provided with holes arranged to register and permit a jet of oil to escape into the open end of the cylinder, substmitially as described.

3. The combination with a plurality of cylinders and pistons working therein, an oil receptacle extending across the open ends of said cylinders, meansfor supplying oil thereto under pressure, and .means operating intimed relation to the movement of the pistons to cause jets of oil to escape intermittentlyfrom said receptacle into the open ends oi the cylinders, substantially as described. V

4. The combination with the cylinders, pistons, crankshaft and crank casing of a multiple cylinder motor, of a hollow shaft within the casing extending across the open ends of the cylinders, a. sleeve beneath each cylinder through which the hollow shaft passes, "means for supplying the hollow shaft with'oil under pressure, and means for rotating'the hollow shaft in timed rela ion to the movements of the pistons, said nollow shaft andsleeves being provided. with holes arranged to register and permit jets of oilto be thrown into the open ends of the cylinders. substantially as described.

The'combination with the parts of the apparatus to be oiled, of an oil receptacle pro ided with a discharge orifice, said orifice being located in fixed position and separated from the parts to be oiled by an intervening space, means for creating pressure on' the oil, means for controlling the disv charge of oil from the 'orificeand across .the

spaceon to the pants to be-oiled and mechanism for actuatinfi'the said means to cause the intermittent scharge of oil. from said orifice at predetermined times to the parts of the agparatus to be as descri ed.

oiled, substantially I In testimony whereof we afiix our signe- 'tures, in presence of two witnesses.
